If you’ve ever searched for the best water purifier in India, you’ve probably come across the term RO purifier. But what does RO actually mean?
👉 The RO full form in water purifier is Reverse Osmosis, one of the most advanced and widely used technologies for purifying drinking water.
In this blog, we’ll break down:
What does RO full form mean?
How reverse osmosis works
Benefits and disadvantages of RO purifiers
Advanced features like pumps and EDI
Why Romegamart is the best place to buy domestic RO systems and spare parts
RO = Reverse Osmosis
A water purification process that uses a semipermeable membrane to remove dissolved salts, heavy metals, and harmful contaminants.
Multistage Filtration System
Sediment Filter → Removes dust, rust, and visible particles
Carbon Filter → Absorbs chlorine, organic impurities, and odor
RO Membrane → Removes 95–99% of dissolved solids (TDS), fluoride, arsenic, lead, PFAS, and more
Post-Carbon Filter → Improves taste and odor for final drinking water
Water Pressure
RO works by applying pressure (2–17 bar for fresh water, up to 80 bar for seawater).
Booster pumps are often used in areas with low water pressure.
Permeate vs Reject Water
Permeate (Purified Water): Safe drinking water after filtration
Reject (Waste Water): Brine carrying contaminants, usually 2–3 liters wasted per 1 liter of clean water
✅ High Purity – Removes TDS, heavy metals, pesticides, fluoride, nitrates, and harmful microorganisms
✅ Better Taste & Odor – Carbon stages improve water flavor
✅ Health Safety – Ensures safe drinking water even in high-TDS regions like Delhi, Rajasthan, Gujarat
✅ Industrial Use – Prevents scaling, ensures compliance with safety standards, used in pharma, food & beverages, electronics
✅ Eco-Friendly – Reduces dependence on bottled water
💡 Did you know? According to BIS (Bureau of Indian Standards), safe drinking water must have TDS < 500 mg/L. RO is the most reliable method to achieve this.
While RO is powerful, it comes with some challenges:
❌ Water Wastage: Conventional RO units waste 3–25 liters per 1 liter purified
❌ Mineral Removal: Removes beneficial calcium & magnesium → solution: remineralization filters
❌ Membrane Fouling/Scaling: Needs maintenance and pre-filters to avoid clogging
❌ Plastic & Disposal Concerns: Used RO membranes end up in landfills; recycling solutions are emerging
Install permeate pumps to reduce waste by up to 80%
Use alkaline cartridges for mineral balance
Opt for WaterSense-certified RO purifiers for efficiency
Booster Pumps – Maintain adequate pressure when feed water pressure is low
Permeate Pumps – Enhance efficiency and reduce waste water
Electrodeionization (EDI) – Used in industries for ultra-pure water after RO

Q1: What is the RO full form in water purifier?
A: RO stands for Reverse Osmosis, a process where water is forced through a membrane to remove contaminants.
Q2: Is RO water safe for health?
A: Yes. However, remineralization filters are recommended for balanced minerals.
Q3: Does RO waste water?
A: Yes, traditional models waste 2–3 liters per 1 liter purified. High-efficiency RO purifiers can reduce wastage.
Q4: Which is better – RO or UV?
A: RO is better for high TDS water, while UV is effective for microbial contamination. Many modern purifiers combine RO+UV+UF.
Q5: Where can I buy the best RO water purifiers in India?
A: Visit Romegamart.com for verified suppliers and wholesale deals.
